Abstract (en)
[origin: EP0631167A1] A head-up display includes an image display means and a hologram as reflection means for reflecting display beams emitted from the display, wherein an image is reflected inside a windshield and the image is formed at the front of, and outside, the windshield. Concave mirrors having different focal lenghts in different directions are recorded on the hologram as the reflection means so as to offset distortion of the display image resulting from the radius of curvature of the windshield. According to this construction, the display image free from distortion can be displayed on the windshield. <IMAGE>
